The World of Life about Us--Distribution of Plants and Animals

Indicates that the distribution of plants and animals is determined by their rate of increase and ability to disperse and by physical and biological barriers. Discusses each of these, using specific species as examples. Shows through the study of fossils that many animals have become extinct in areas where they were once abundant. Stresses the fact that man must be careful that he does not upset the balanced world, which has supported him for a million years.
